I Application filed November 17, 1914. Serial No. 872,612.

To all whom it may concern:

Be it lmown that we, ALVA G. PIERCE and Gnoncn G. KAUFMAN, citizens of the United States, residing at La Fayette, in the county of Tippecanoe and State of Indiana, have invented new and useful Improvements in Jordan Shafts for Paper Stock Refining Engines, of which the following is a specification.

This invention relates to improvements in the construction of the Jordan shaft of a paperstock refining engine and especially with reference to the provision of a conical core on the shaft and a pair of frusto-conical jackets which are adapted to be detachably secured on the core and which are provided with knives, so that the knives may be readily and securely placed on the shaft are prevented from getting out of order during the operation of the engine in refining grades of stock and so that the knives may be readily The invention consists in the construction, combination and arrangement of devices hereinafter described and claimed.

In the accompanying drawings :Figure 1' is an elevation of a Jordan shaft construct ed in accordance with our invention, Fig. 2 is a central longitudinal sectional view of the same. Figs 3-4: are transverse sectional views of the same on the planes indicated by the lines w-a and 71-?) respectively of Fig.2. i

In accordance with our invention we provide a conical core 1 which is detachably secured on the shaft 2 by means of a key 3 which engagesa slot 4: in the shaft. The core is provided on one side, at its larger and smaller ends with key ways- 5-6, re-

removed and replaced when desired.

and said jackets are securely and yet detachably held on the core by keys 13-14. The knife jackets are also secured together at their meeting ends by a dowel pin 15 which is here shown as projecting from the smaller end of the jacket 8 and entering openings 16 in the larger end of the jacket 7.

The parts of our improved Jordan shaft may be very readily installed, the knives are securely held so that there is no danger of tearing up, and the power required to operate the engine is materially reduced.

Having thus described our invention, we claim A Jordan shaft having a core knife jackets on the core and keys detachably securing the knife jackets to the core, the jackets being provided at their opposing ends with means to detachably secure them together.

In testimony whereof weaflix our signatures in presence of two witnesses.
